Water water water water!
So there were two things going on last weekend:
1) We had a major winterstorm coming in from the southwest, which pushed the water of the Baltic Sea our way. We also had a deep low pressure. (... course, you tend to have that, when you talk major storms.)

Here's a pic of the local result, Sunday midday. It's not all that bad, you just can't walk the usual routes along the shoreline. The central marketplace in Helsinki was flooded (1.5 meters above normal), and a few major roads were closed due to floods. And of course there were flooded basements (and a few flooded streets) all along the coast.
Flooding of the Baltic is practially unheard of, up here. This was a record flood: they've been measuring water levels in Helsinki since 1904 and this is the first time we hit 151 cm. The previous record was 136 cm (27.1.1990). Dunno what the record before that was.
What we got was mild if compared to Estonia (1.7 meters above normal, and the full brunt of the storm) and St. Petersburg (+2.5 meters).
2) The southern storm brought warmer temperatures (would you believe +9 C in January? Me neither.), so all the snow was melting all over the place (they're still all white and pretty a hundred km to the north and east of us - it's just wet and black and dreary along the coast), so the local river (Vantaanjoki) was extremely busy.

Here's a pic of the waterfall. I can't remember having seen the water going quite that horizontally over the rim earlier, even though the river does have major snowmelts every spring. Floodings upriver are normal in spring. Not in mid-winter.
(I would have included links to "normal" pics of the waterfall, but alas, nobody has seen fit to put such pics online.)

And I don't remember seeing the water come up from beneath the wooden floorboards of the waterfall platform before, earlier. 'course, that could just be because I've missed the busiest spring flood days, in previous years - I don't go there to have a look every day, after all.
The power of nature, eh? I'd love for our real winter to resume. It's been here, now it's gone, and I prefer frosty white winters to wet black ones.
